I aim to make an AI that you can talk to, and at some point, I'll add some games like Blackjack and Rock Paper Scissors to play with the AI.

The chat function will be the main point of this AI, and it will learn by storing information in file(s). For example, if it doesn't know what sushi is, you could say "a type of food", then it would store this in a file, and it would load the information when necessary.

I'm planning on doing this in C++.

It is being faced with some scrutiny, as I am apparently "creating friends". I suppose I am, but I'm improving my coding ability at the same time.

I need ideas for how to lay out the program, like, how would I lay out the code so that the AI would search through its built-in responses based on whether or not your statement or questions contained key words or phrases? Etcetc, I'll type more tomorrow morning, I'm tired.
